Top Express.js Agencies

Express.js is a lightweight web framework for Node.js used to build APIs, web servers, and backend applications. It provides routing, middleware, request and response handling, and a simple foundation that developers can extend with additional packages. Express is commonly used for REST APIs, authentication services, ecommerce backends, dashboards, and integrations. Its minimal structure gives teams flexibility over database libraries, validation, authentication, testing, and application architecture.

For projects using Express.js, teams should consider the application's requirements, expected scale, integration points, deployment environment, testing approach, and long-term maintenance. Choosing the technology should also take into account the existing skills of the development team and the libraries or services already used by the product.
